nji

a web framework for write API quickly.

feature

• simplify routing management
• parameter verification without go tag
• configurable dependency injection

example

the user could write HTTP handler like this:

// ./_example/view.get_query_params.go
type get_query_params struct {
	nji.Route[route.GET, route.ROOT] // define URL
    // and will got this URL : [GET] http://127.0.0.1:8080/get_query_params?A=phonenumberis&B=12345678901

	A plugins.QueryParam[schema.Must] // define `plugin` to inject args automatically
	B plugins.QueryParam[struct {
		schema.Must
		schema.IsPhoneNumber // use generic T as metadata for parameter verification
	}]
}

func (v *get_query_params) Handle(c *nji.Context) {
	c.Writer.WriteString(v.A.Value + v.B.Value)
}

func main() {
	app := nji.Default()
	nji.Register[get_query_params](app)
	app.Run(":8080")
}

instead of:

func get_query_params(c *gin.Context) {
    a, ok := c.GetQuery("A")
    if !ok {
        // ...
    }
    b, ok := c.GetQuery("B")
    if !ok {
        // ...
    }
    if checkIsPhoneNumber(b) {
        // ...
    }

    c.Writer.WriteString(v.A.Value + v.B.Value)
}

func main() {
	router := gin.Default()
	router.POST("/get_query_params", get_query_params)
	router.Run(":8080")
}
